DIY A-B Switcher

Luke's student Siddharth Kothari gifted him a "A-B Switcher" which he made on his own as a DIY Project. The device can be used to connect any two devices (like 2 guitars or 2 amplifiers, etc) and switch between the two by just pressing a switch! Siddharth is studying in the 12th standard and learns guitars from Luke.
